Power Train ­ Engine Power Train ­ Transmission Structures The Cat® C15 engine with ACERTTM The Cat® seven-speed power shift The 770 features a mild-steel, box-section Technology uses advanced engine transmission matched with the Cat C15 type frame to deliver durability and long technology to reduce emissions engine with ACERT Technology provides life with low operating costs. The turbocharged, constant power and efficiency over a forgings are strategically placed in highaftercooled 6-cylinder engine has faster wide operating speed range for optimal stress areas to evenly distribute stresses response for superior performance in power train performance. 4 Serviceability Truck Body Systems Information and Monitoring Systems Standard on the 770, the Cat Messenger system provides real-time engine performance and operating data. [. . . ] The primary piston hydraulically actuates both service and retarding functions. The secondary piston is spring-applied and held in the disengaged position by hydraulic pressure. If hydraulic system pressure drops below a specified level, the springapplied secondary piston automatically applies the brakes. The 770 parking brake function is provided by the spring-applied function in each of the rear oil-cooled disc brakes. The 770 parking brake is capable of holding the machine with a rated load on grades up to 15 percent. Automatic Retarder Control (ARC). Standard ARC electronically controls braking on grade to maintain engine at approximately 2, 200 rpm (adjustable from 1, 950-2, 200 rpm in increments of 10). ARC is deactivated when the operator applies the brakes or throttle. 2, 500 2, 000 · Ease of Operation. ARC increases operating ease, resulting in greater operator confidence with less fatigue. Automatically activates ARC when engine speed exceeds factory preset levels, regardless of operator inputs, to avoid potentially damaging engine overspeeds. Electronically monitors and controls rear wheel slippage for greater traction and enhanced truck performance in poor underfoot conditions. If slippage exceeds a set limit, the oil-cooled disc brakes engage to slow the spinning wheel. Torque is then automatically transferred to the wheel with better traction. Optional Compression Brake is integrated with Automatic Retarder Control (ARC) to provide up to 35 percent higher downhill travel speed and reduce wear on brake components. 1, 500 1, 000 500 0 10 20 30 40 50 Time (Seconds) 60 70 With Automatic Retarder Control (average speed, 1, 950 rpm) With Manual Retarder Control (average speed, 1, 730 rpm) · Faster Speeds. ARC allows the operator to maintain optimum engine speeds for up to 15 percent faster downhill hauls and greater productivity. Automatic brake modulation offers a smoother ride and better control in slippery conditions, allowing the operator to concentrate on driving. 13 Serviceability Less time spent on maintenance means more time on haul roads. · Transmission, Hoist and Steering Lockout Switch. The 770 features an all-new transmission, hoist and steering lockout mode. This feature disables the steering, hoist and transmission hydraulics, and sets the parking brake while the engine is running, allowing maintenance and trouble-shooting on the truck. The operator can use this feature to take S·O·SSM analysis samples. Ground-level access to circuit breakers are now provided for engine control, alternator and main electrical breakers. S·O·S sampling valves speed sampling and analysis reliability. Disconnect valves are conveniently located throughout the hydraulic systems for easy pressure testing. Radial seal air filters are easy to change, reducing time required for air filter maintenance.
